Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

In a recent article [*] an nxn aperture was described for imaging. While square apertures are commonly used in medical applications, more general rectangular apertures may be used in other applications. A general rectangular mask of dimensions nxm is shown in Fig. 1 as a binary array. The decoding array is of the form shown in Fig. 2, in which: In the case of n=m these values reduce to those in the article referred to. The mask has an open area which is the fraction (n+m-2)/nm of the total mask area. Reference A. R. Gourlay, "Coded Aperture for Tomographic Imaging," IBM Technical Disclosure Bulletin 24, 2848-2849 (November 1981).

Rectangular Coded Aperture

In a recent article [*] an nxn aperture was described for imaging. While square
apertures are commonly used in medical applications, more general rectangular
apertures may be used in other applications. A general rectangular mask of
dimensions nxm is shown in Fig. 1 as a binary array. The decoding array is of
the form shown in Fig. 2, in which: In the case of n=m these values reduce to
those in the article referred to. The mask has an open area which is the fraction
(n+m-2)/nm of the total mask area. Reference A. R. Gourlay, "Coded Aperture for
Tomographic Imaging," IBM Technical Disclosure Bulletin 24, 2848-2849
(November 1981).
